Top 10 Hardest Mario & Luigi Bosses

The Top Ten
1 Dreamy Bowser

Dreamy Bowser's battle is not your average foe. He is extremely annoying. First of all, from the start of the fight, in order to get a hit on his body, you have to kill his right arm (which isn't too hard, it can get taken out easily by Star Rocket or Zee Egg), but the main issue is that every 2 turns, he will summon a horde of minions and go to the background to heal, INCLUDING HIS RIGHT ARM. Making you have to destroy it again to land body blows. Then his other attacks, first of all there is the attack where he chases you while breathing rainbow fire. The issue here is that the fire doesn't move at the same time Bowser does, meaning you have to predict it. If it hits you'll lose about half your health from just one strike. He can also call a Airtub, which will then follow you before going into the background. If your strategy relies on setting up barriers with Guard Shell and the Guard Badge, they can whittle down your shields fairly quickly over time, and having some 240 HP with ...more

Between having some of the highest stats in the series, tricky patterns, minion summoning, and one of the best boss themes ever in my opinion, he more than qualifies.

It was one an incredibly tough boss fight. I didn't vote Cackletta Soul because it was hard because it was cheap. This one isn't cheap-it's just really hard!

Even when I had very good gear that lets you have infinite items, and heals BP and HP a good amount each turn, I still almost died to this boss. The hardest by far.

2 Cackletta Soul

In the original games, this boss is very likely to go first, meaning that there's a chance of losing immediately.

The remake makes this boss even harder due to two changes:
1) Her arms become elemental, meaning that Fire and Thunder Bros. (and their stronger counterparts) can heal her arms if your attack targets the wrong arm.
2) There was an attack she uses in the original that requires you to knock back energy orbs, damaging her. In the remake, this attack doesn't reflect, so no loads of damage to the boss when this move is used. The remake also gave the bestiary better stats, somher attacks hits harder.

Reason why final bosses like cackletta soul and dreamy bowser make the list is because their battles are extended. They force you to attack their appendages and other such targets. So when you fight the boss it is longer then it is hard. You technically have infinite mushrooms and healing beforehand. It simply becomes a matter when the boss dies, not if. Trust me, whenever I fight a one of these bosses I pray that they will be hard. I WANT MY ASS TO BE KICKED GOD DAMN IT.
So unless you're either impatient and underleveled, or just less than 8 years old these guys aren't that tough.

I recently played through all of Superstar Saga and fought every enemy I could. I used every bean coffee, bought the best gear, and never once died. Then Cackletta came by. My Mario bros were able to one shot nearly every Koopaling, yet Cackletta absolutely destroyed me. After about 15 attempts, I managed to beat her, and that was with level 40-45 bros, making her an unmistakingly bullcrap boss.

The fight is very long, and her attacks are very dangerous. At least, they are not too crazy, execepts for the attack where she throws balls of energy at you that are green and pink. This is the only fight in the series where a boss is so hard that it's actually a bad thing. I find Dark Fawful, Elder Princess Shroob, Kamek from Dream Team hard too but, at least they are a good challenge. This boss is annoying.

3 Princess Shroob / Elder Princess Shroob

After destroying Princess Shroob, you think that your journey finally comes to an end, and that the princess is safe...well, meet Elder Princess Shroob everyone! The supreme ruler of the Shroobs, this monster has a whopping 3,500 hp, with many attacks that can do massive damage...and when you finally destroy her, she activates her crown...and another 3,000 health. Except this time, you have to disable her legs and her crown to be able to do more than 1 damage to her at a time. AND she attacks you multiple times per turn, far more than Cackletta does. There is no debate about it; Elder Princess Shroob is the hardest boss in the M&L series.

I know, right?! Nonetheless, M&L: PIT is the best Mario & Luigi game ever.

Mario & Luigi: Partners in Time is top 1 on best Mario & Luigi games, with Superstar Saga being top 2, Bowser's Inside Story being top 3 & Dream Team being top 4.

Was extremely hard; all my bros were overleveled and after 30 minutes I barely scraped by

These and Shrowser were the only bosses in the game that weren't just absolute jokes.

4 Zee Keeper

His attacks are REALLY strong, and hard to dodge. You're either lucky or skilled if you can dodge all (or at least most) of his attacks in the dimensional rift.

A pretty fun boss battle with decent challenge. Except for the motion controls glitch. That's probably why this is here.

I hate it when he makes a weird dimension (even though I already bet him).

The rift was way to easy

5 Memory ML

Definitely the most creative boss, with ALL attacks being incredibly original. And in case anybody does not know, when the Bowser memory L gets chased by the boo, the "Luigi" would ALWAYS jump over your head and the boo would ALWAYS go straight for you. But you can just jump on the boo and end the chase.

Yeah right. seriously megasparklegoomba in paper Mario sticker star is harder than those two wimps

Easiest I am so glad to pass

6 Dark Fawful

Hi I think that just looks like a old sparked women with no legs attached to it

Really? I found him rather easy. Compared to Ice Midbus, of course.

One ahots you and I hate it

7 Elder Shrooboid

Hi I think that just looks like a nice red hot pamkim

The 4 turns till game over and spikey head screwed me over way too many times you need more then 4 turns

8 Dark Star X

He has so much HP. The biggest problem? Not enough turns if your going on the path to Bowser X, who did 253 damage to the bros.

That guy sucked to beat with him having like nine fakes instead of six

Hi I think that just looks like a dark old star

can't beat it too powerful

9 Bowser X

He’s number 3 in hardest Mario bosses, but not even top 5 in hardest Mario and Luigi bosses? Bowser x should either number 1 or number 2 behind cackletta’s soul.

This guy should be the flipping number 1! I completely underestimated him on my first tIme. I was like "oh yeah this guy should be difficult. Nothing I can't manage" but I was clearly blind on how powerful he is. His speed made it hard to dodge, and when I got hit, I was like "253 damage?!?!?! Are you flipping kidding me?!?!?! This boss is already a nightmare! " The item stealing thing isn't that bad, unless it's healing items or OP Bros Attacks. I had so many turns gone. number 1 by far. Cackletta's Soul is NOTHING compared to this.

This guy is a nightmare. First of all, you have 35 turns to beat him AND every other battle ring boss. Second, even if you're a master magic window attacker, it's incredibly hard, since he INHALES your bros. items. His attacks are hard to dodge, plus they do insane amounts of damage! The first time I played this game, it took me 10 TRIES OF PURE AGONY just to beat him! The only reason I won the 10th time is because I Magic Window'd 5,000 of his HP. Even dealing the last 2,000 damage is brutal! How is he not #1?!

So on the ranker for the hardest Mario bosses all time bowser x is number 3 behind the shadow queen and Cackletta soul, but not even top ten in the Mario and Luigi series? Also how is dark star x higher than bowser x, bowser has twice his health and likely twice his attack, and I know he has higher defense too. Almost all of his attacks are capable of doing 200+ damage easily, there’s a turn limit, it’s at the end of a boss rush, AND he sucks in your special attacks. Recommended level to fight him is level 50, and he’s still super hard the. For comparison Cackletta’s soul recommended level is 40. The only other boss that should be compared to bowser x is Cackletta’s soul. Those two bosses are the hardest in this series, and I am a huge fan of the series and I know all the bosses, those are the only two bosses that should be considered number one. The other one should be number two.

10 Big Massif

I think it was kinda hard the attacks he made.

I found him pretty easy

The Contenders
11 Antasma X

...I can not tell you how much I HATE Antasma even in his normal form for his attacks are super deadly and can weaken you one attacks is when he turns into a hundred bats (this attacks is used in the very very first fight with him) bit the probably is ther Eid chance if you get hit you will fall asleep and Antasma will put you in a nightmare where he will attack you with fire balls untill you jump into a portal that wakes you go in the wrong one and you got to avoid a bunch of attacks and you will be stuck in the nightmare into you either die or go in the right portal and that is just one of his attacks also in his X form his attacks in increase a lot he is a incredible pain but it feels sooo good to kill him be really prepared for a bad time

Antasma X as number 10. Probably because not many people went up against the bastard. Just look. The game intentionally heals you 30 Hp per turn and gives you the chance to gain 50 more Hp in the dream. Not many different attacks but it is one repetitive nightmare for those who wanted more antasma. The guy could well kill you easily in his first turn, most likely from panicking and bumping into all his attacks. Cackletta had to troll you with one Hp. This guy doesn't.

Unless you already mastered the game this guy will own you. Especially if you're under levelled. Trust me that when I fought this guy on normal mode it took a lot of tries.
But in hard mode I learned, got the all the ultimate gear and took this guy out no sweat. Basically, this battle is determined by the 40 hours you spent trying to get the duplex crown.

The original Antasma was arguably my favorite fight in the game, and it certainly delivered on difficulty, but Antasma X was NIGHTMARISH. You get only 14 turns to defeat him-and if he sends you to the nightmare world, you lose one. You'll need to use as many Luiginary attacks as possible if you even want a chance of taking him down.

12 Queen Bean

This one's easy!

13 Ludwig and Larry (Mario & Luigi: Paper Jam)

Honestly, both the first and second battle were difficult, even for me. Many people consider this the most difficult boss in Paper Jam. I think they should be fairly high on the list.

This boss battle proves difficult due to at least two things... One attack that I’ve noticed that gives many people trouble is Ludwig’s double magic blast attack. The battle cards are also a problem. In the second battle, there is a card that can kill all three players in one hit, providing Paper Mario’s copies aren’t stacked thickly enough to block it. Besides those things, their attacks are often difficult to avoid, and they both have very high hp, especially Ludwig. Therefore, I cast my personal vote for these two. Cackletta wasn’t even that bad, in my opinion.

Yeah, it took me forever to get through these guys. Ludwig was a big problem.

Really hard Ludwig was really hard to beat

14 Bowser Jr. (Dream Team) Bowser Jr., or sometimes simply Jr., is a video game character who appears in Nintendo's Mario franchise as the secondary antagonist. He is the youngest son of the series' primary antagonist, Bowser.

I mean look at it. You got 45 turns to beat The other bosses in the battle ring, including the big bad antasma x. Then you got this little dude stealing your moves when you have like 5 turns left. Bowser Jr. is hard

I haven't tried the fight yet but he is always stealing so I know he's super hard.

love little jr

15 Fawful Express

The DS' shoddy mic makes it hard to land Bowser's fire attacks to Excellents, which is essential for this boss. With annoying attacks and DS' mic, this is the only boss besides Bowser X that took me several tries to beat. By far the hardest of the giant fights still.

Whaa? Fawful express? Hard? When I played bowser's inside story I thought it was very easy (I actually found all giant battles very easy, but I never reached the point where you fight peach's castle)

Made way easier in the remake, replacing mic input with tapping the screen at the right time.

Extremely hard with the crappy ds microphone

16 Shiny RoboBowser (Mario & Luigi: Paper Jam)

Takes a LONG time to beat and at the level I was at, almost every attack could kill me in one hit!

By FAR the hardest non-bonus boss in the series

his looks would tell you how good he is

ok this looks awesome

17 Giant Bowser (Dream Team)

It was all easy until the star driver and its retarded controls. I was as mad as hell when he was revived, damn you Kamek I'm still trying to get past this abomination, thanks for wasting countless hours of my childhood Nintendo!

I like the big bowser boss fights

Duuuuuuuuuuude this guy takes around three turns before you can do ONE it took me months and around 20 tries to beat him.

18 Blizzard Midbus
19 Dark Star Core
20 Fawful (Superstar Saga) Fawful, known in Japan as Gerakobits, is a fictional character appearing in the Mario & Luigi series of role-playing video games developed by AlphaDream.

If you're talking about the second fight then yeah. Very hard and his shield is very annoying as well!

21 Cackletta (1st fight)

Her attacks are fast-paced and do tons of damage, and it can catch you by surprise the first time.

This was pretty hard! Her attacks can be very random and it's hard to time your jumps right!

22 Bowser Jr (Paper Jam)

He is just our right INSANITY

23 Hermie III

This guy was tough on my first playthrough, and still gives me trouble to this day.

This guy had way too much HP to the point it takes forever to make him lose half of the HP!

he had to much HP my dude he killed over 9000 times

24 Bob Landrik

Obviously the hardest! HE DID A WHOPPING 456 DAMAGE TO ME!

25 Alpha Kretin (Bowser's Inside Story)

This boss was hard! I want to have the remake let you play as Starlow during the fight instead of Luigi.
